We ordered this mattress for our guest bedroom and couldn’t be happier with it.  It came rolled up in a box, worried me at first, but it quickly expanded into a large plush mattress.  It even came with an envelope opener and easy instructions to open the vacuum sealed bag.  The mattress itself seems very sturdy and is definitely comfortable.  The ultra plush top is like laying on a cloud.  Highly recommend and would surely order another one!
